This invention relates dered or beaded necks.

What I aim to do is vto closure for bottles of the type Aras arena BOTTLE onosonn.

to an improved having shoulprovide a novel bottle closure which can be used in lieu of the common crown cap now universally used,

the present closure ybeing such in construction tliatyit obviates the necessity of requiring special machines for capping bottles and subjecting them to breakage;

advantageous at the it will be found the new cap be found time of application, but

Not only will equall5 as advantageous when removing the cap the use for it can be readily.. taken oi Without of a special-bottle opener and Without causing breakage of the glass such as happens when crowncaps are used.

lt. is also a feature of, the present invention toprovide a structure an effective lluid'seal, yet

escape o' destructive gases upon the cap slightly.

which Will form will permit the loosening As a result of the foregoing, ther closure will be oundcomparatively simple in construction and inexpensive to use 'despite the act'that it may cost fraction more in money to manitfacture, this being truc in view 01"' the that the construction provided assures the liquid tight s eal and safety means for gradually removing explosive gases.

Other features and adva ntages of the invention will become apparent from the following description and drawings.

. In the accompanying part of this specification, numerals are employed parts throughout the same drawing 'formingand in which like to designate like Figure l discloses a side elevation of a bottle closure constructed inaccordancelwith this invention, showing the same applied to \li",vu re 2 shows a central Vertical section \throug`h Figure 1.

.Figu'c ,3 is a cross sectiontaken on line In carrying out the invention, .I employ 'a substantially cylindrical split sleeve 1 which prodvided atvits top with an forming a shoulder one of the beads B and which is inturned flange 2 for engagement with on the bottle neck N.

.The sleeve is indented with annular grooves 4 providing screw threads. ocperative with the sl eeve is a closing opening 8 through Awhich a locking pin 9 is i .Applicationled .Tune 24, 1924i Serial No. 72:2,10f

cap 5 Whichis adapted to telescopically receive the upper portion ot sleeve and which has its shirt portion pri'ivided with screw threads 6 for engaging the threads of the sleeve. A packing dislr 'Y is adapted to bc interposed between ythe bottle neck and the cap as shown more clearly in Figure 2. The skirt of the cap is provided with an adapted to project, this locking pin being carried b v `the free end of a spring 10 fastened to the cap. The head on the inner end of the locking pin is adapted to be positioned in the slot formed by the spaced split ends of the sleeve` This arrangen'ient prevents relative rotation or' the cap with respect to the sleeve. l might state here that the openf ing- 8 of a size to permit the pin to be entirely Withdrawn iiheiethrough to facilitate screwing on of the cap. Furthern'iore, l might state that while l have vshown the slotin the sleeve as being 'lisposed.substantially vertical, l Wish it.""to be understood that vit may, if desired, be disposed diagc- Nl nally.

n practice, 'the is slipped over the neck of bottle prior to the attachi'nei'it of the cap. The in the sleeve permits it to expand to accommodate the diameter or the bottle and since the sleeve will preferably be of resilient material, its flange forming shoulder will snap beneath the bead on the. bottle to hold the sleeve in place. With the sleeve in place,.the cap is simply threaded onto the sleeve by rotation of one with respect to the other. At this time, the spring l0 is held outwardly with the finger to pre1 vent interference of the locking pin with the. relative rotation' of the parte. es sooii as the cap has been screwed on s cieuti'jf air tight, and assuming 'that the loosing pin is then opposite the slet, the spring is released and the pin is projected'into the sist to serve as a lock to th n prevent further rotation oi the cap withA aspect to the sleeve. W'herethe closures are used simply for domeetic purposes, l have found that the. locking pin and spring` may be eliminated,- ili' v desired. lYhere, however, the bottle is t0 'les be shipped, it is much safer to use the suplemental locking device.

Although l have shown and described the specific embodiment ol the invention, itis to be understood that minor changes ceining within' the scope of the appended claims,

I claim:

l. In combination, a bottle having a neck and exterior bead thereon, a sleeve about the neck and having an inturned flange at its u per end opposed to said bead and also aving intermediate portions bearing against the outer side ot' the neck, and a screw-threaded cap .detaehably connected with said sleeve.

2. A bottle closure comprising a resilient split sleeve adapted to surround a beaded bottle neck, said sleeve having its upper end inturned to provide a sto flange for engagement with the bead an being 'further provided with an exterior indenture and an interior projection formin a screw thread, a screw threaded cap a apted to threadedly engage said sleeve, and a locking device carried by said cap and adapted to cooperate with the slot rovided between the spaced ends of the s eeve -for preventing relative rotation of the cap to the sleeve.

3. A bottle closure corn rising a resilient Il split sleeve having one en directly laterally inward to provide a stop mange, said sleeve being provided with an annular indentation forming a screw thread, a closing cap having its skirt provided with a screw thread for cooperation with the aforesaid screw thread,

said skirt being also formed with an opening, a spring carried by said cap, and a laterally extending pin carried by the free end of the spring and ada ted t0 project through the opening in sai slot formed between the spaced ends of said split sleeve.

4. A bottle closure comprising a sheet metal sleeve split throu hout its height and adapted to surround a ottle neck provided VALENTINE MLETSCHNIG.
